What is SailfishOS?

Sailfish OS is a GNU/Linux based mobile operating system, which is gesture-driven for the ease of use. It runs natively as glibc (not Android's bionic), has bash and busybox (not toolbox), uses Qt for UX, and other opensource projects in its middleware -- which basically is just like a Linux on your desktop, but needs Android drivers for some of device's hardware.
